- This invention relates to a unit for illuminating the peripheral surface and surrounding portion of each reel in a slot machine wherein when a plurality of reels each with a plurality of symbols provided on the peripheral surface are stopped, if a specific combination of the symbols on the reels holds on a validated pay line, the game state changes (a transition is made to a bonus game, for example).
- A reel-type slot machine is known as a gaming machine installed in a casino, etc. Such a slot machine is provided in the front center of the machine with a display window for displaying the symbols provided on the peripheral surfaces of the reels, and also comprises a coin slot, a start lever, etc., disposed at appropriate positions of the machine front. As shown in FIG. 13, a plurality of
reels 1 and abacklight illumination unit 2 for illuminating the peripheral surface of eachreel 1 are placed inside the display window. - The
illumination unit 2 has alight source 3 such as a fluorescent lamp or an electric light bulb and aframe member 4 placed in front of thelight source 3. Theframe member 4 is made of a colorless or color-tinted transparent plate of acrylic, etc., and afront face 4 a is made translucent like frosted glass so that light from thelight source 3, incident from arear face 4 b is emitted while it is scattered. When power is turned on, theillumination unit 2 illuminates the peripheral surfaces of the reels, making the symbols on the reels easy to see from the outside through the display window during the game. - In this kind of slot machine, when a coin is input and the start lever is operated, all reels start to rotate all at once and then stop. When all reels stop, if the symbols on the reels stopped on at least one validated pay line of a plurality of pay lines become a predetermined combination, a predetermined number of coins are paid out as an award. When a winning is thus determined, the
illumination unit 2 performs predetermined lighting, blinking operation for illuminating the peripheral surfaces and surrounding portions of the reels to enhance the stage effects. - In recent slot machines, it has been common practice to adopt a system wherein to give the opportunity for the player to get a large amount of award, when a specific combination of the symbols on the reels holds on the validated pay line, the player wins a special prize and is allowed to make a transition from the normal game to plural turns of bonus games. In the configuration in which the game situation thus changes, the illumination at the normal game time and that at the bonus game time are changed appropriately and further specific illumination is conducted at the game state transition time, whereby the stage effects can be more enhanced.

- FIG. 1 shows an illumination unit according to a first embodiment of the invention. The illumination unit has a
transparent frame member 10 placed in the rear side of a symbol display window (not shown) of a slot machine and in front of a plurality ofreels 14 each with a plurality of symbols provided on the peripheral surface. - The
transparent frame member 10 has afront face 10 a and arear face 10 b as main faces and side end faces 10 c connecting them. It is formed with throughholes 10 d as many as the number of the reels so as to penetrate theframe member 10 from thefront face 10 a to therear face 10 b. The throughholes 10 d are positioned in the front side of thereels 14, as shown in FIG. 2. - The size of a
front face 10 a side opening of each throughhole 10 d is formed larger than that of arear face 10 b side opening, whereby aninner end face 10 e of each throughhole 10 d connecting both the openings is a slope widening toward thefront face 10 a, as shown in FIGS. 1 and 2. The surface of eachinner end face 10 e is a light scatter face like frosted glass. -
Light 15 emitted from alight source 11 is incident on the side end faces 10 e of thetransparent frame member 10 and propagates inside theframe member 10. At this time, each end face 10 e formed as the light scatter face behaves as an exit of the propagating light (light director). A part of theincidence light 15 goes directly toward thelight director 10 e as indicated by the solid line in FIG. 2 and another part goes toward thelight director 10 e while it is totally reflected on the inner face of the frame member, as indicated by the dashed line in FIG. 2. The player situated in front of the display window visually recognizes only the emitted light from thelight directors 10 e and sees as each reel is surrounded by a light frame. - The inclination angle of the
light director 10 e can be set appropriately in the range in which it can guide the incidence light 15 to the outside of the display window. - As the
light source 11, various known light sources of a LED, a fluorescent lamp, etc., can be adopted. Thelight source 11 may be a single-color light source for emitting a predetermined color (or a combination of a white color source and a filter for providing a predetermined color), but preferably an RGB light source unit that can emit red light, green light, and blue right at the same time and enables the emitted light strength to be adjusted appropriately. The light amount ratio of red, green, and blue of the primary colors of light is set appropriately, whereby light of any desired color can be provided For example, a light condenser for condensing emitted light of each color and making the light incident on the side end face 10 c of theframe member 10 can be combined with a light source unit having LEDs or fluorescent lamps of the primary colors. - When each color light incident from the side end face10 c propagates inside the
frame member 10 and is emitted from thelight director 10 e, the colors can be mixed by the effect of the light scatter faces to provide any desired color. - A
controller 12 controls the color of light emitted from thelight source 11 and the operation of lighting, blinking, flashing, etc., in response to the situation of game activation, normal gaming, transition to a bonus game, etc. For example, at the transition time to a bonus game, the light amount ratio of red, green, and blue making up the light illuminating the surroundings of the reels at the normal game time is changed to another light amount ratio for changing the color and way of illumination is performed, whereby the stage effects responsive to the situation change of the game can be produced. - Thus, according to the embodiment, the colorful illumination stage effects for the reels of the slot machine can be provided by a very inexpensive configuration.
- A second embodiment of the invention is shown in FIG. 3. In the first embodiment, the
inner end face 10 e of the throughhole 10 d forming the light director is a slope having a straight coss-sectional shape. However, in aframe member 20 in the second embodiment, aslope 20 e having a curved cross-sectional shape is adopted as theinner end face 10 e. The curvature radius of the cross section can be set appropriately in the range in which it can direct incidence light from a light source to the outside of a display window. According to the configuration, if a comparatively inexpensive light source is used, uniform illumination can also be provided. - A third embodiment of the invention is shown in FIG. 4. In the embodiment, a plurality of
light sources single frame member 30 and are totally controlled by acontroller 34. Thelight sources - The principle and the configuration to provide illumination for the surrounding portions of reels are the same as those previously described with reference to FIGS. 1 and 2 in the first embodiment and therefore will not be discussed again in detail. The
controller 34 operates at least one light source in response to the game state. For example, if each light source is implemented as a single-color light source, colors of light from the plurality of light sources are mixed in theframe member 30, so that the colorful illumination stage effects responsive to the game state can be provided. Since thecontroller 34 only switches the light sources to be operated, a simpler configuration can be adopted. - Of course, the
light sources controller 34 may be made to appropriately set the RGB light amount ratio responsive to the game state. In this configuration, more colorful illumination stage effects can be provided. - The configuration in the embodiment can be applied to the
frame member 20 in the second embodiment previously described with reference to FIG. 3. - A fourth embodiment of the invention is shown in FIG. 5. In the embodiment,
